Application filed June 18, 1915. Serial No. 34,802.

of Ohio, have invented,, c ertain new and useful Improvements inBias-Cutter Take- Ups, of which thef following is a speci-.

This inventign relates to a machine for handling fabric,1which has beenprovided with a coat of gum, commonly known as frictioned fabric,designed to be used in the manufacture of pneumatic tire carcasses,after it has been cut into strips of desired width on the bias.

m In the drawing the invention is shown combined with the ordinary biascutter,

- whichvlatter' is shownonly in outline, the details thereof, forming no'part of the present invention. v

Figure 1 is aside elevation. Fig. 2 is a plan. Fig. 8 is a view of therear end of the table from theside opposite Fig. 1.

In making'the ordinary pneumatic tire carcass, it .is the practice tocoat or friction the'fabric on one side with a layer of gum.

The fabric is then wound onto reels with an interposed layer of muslinto prevent 'adhesion, and taken to a cuttim machine which cuts it intostrips of predetermined width at an angle of 45 Inthe operation of. thebias cutting heretofore, the fabric has been led under a verticallyreciprocating knife, which cuts .05 the strips in the book consists of aboard with a number of'st'rips of muslin secured thereto along onelongitudinal edge by a narrow nailing strip. The operation of placingthe bias strips in books is expensive and tedious, as

I it requires the employment of two operturning over the leaves of thebooks before ators at 'the delivery end of the machine, picking the biasfabric oil the belts,'and

placing a new strip therein.

It has been the purpose of this invention toreplace this method ofhandling the bias fabric, by providingla traveling liner upon which thestrips fa and which is'wound up with them in aieompact roll, which isstandards 5 under the frame below the table 8.

ting and packaging of the bias strips may be more rapidly done than bythe old method.

cutter and B'the take-up. The bias cutter is shown in outlineonly, andconsists of and 6, which support a table 7, over which the frictionedfabric Sis In Fig. l A represents generally-the bias guided. The rearend of the table is cut off at an angle of 45, and cohperating with theedge, is a reciprocatlng knife .9, earned by a cross-head 10, sliding onpillars 11,

which are held by the standards at their lower ends, and by brackets onthe standards at their u per ends. The knife is shown, and the fabricdrawn forward over the table and under the knife by reciprocatinggrippers, which are also-not shown, as

moved up and down by a mechanism not they are the equipment of anordinary bias cutter.

To receive the bias strips after they fall I from the cutter, there ismounted a reel of muslin or other liner 13, in standards 14 on a wheeltruck 15, which may be pushed An adjustable brakeband 16'is provided onthe frame, to exert frictional contact on the reel, in order to preventover-running. The truck 15 may be rolled out, and a new liner rollplaced thereon, when the old one is exhausted.

From the reel 13, the liner passes up over an idle roller 17, suspendedfrom the under side of the framework, and then under the cutter and overa table 18, the the liner under the cutter. This table 1s long enough toallow several strips of the bias fabric to be in a position to beinspected .or measured, prior to being wound up. Several. strips areshown passing from the cutter to the winding-up mechanism in Fig. 2.

As designated at B, the winding-up or packaging mechanis consists ofuprights or supports 20, whi i are located at the rear of the table, andare provided at their up er "extremlties with vertical or substantia llyvertical slots or guides, 21. Directly below the guides, is rotatablymounted a drum" 22,

the surface of which is covered with. sand paper or otherwise roughened.-On the up per surface of the drum is placed a reelor take-up roll 23, aspindle 24, of which is guided in the slot 21; As shown, the liner withthe bias strips superimposed thereon, passes between the rolls 22 and23, and as they are moved in the direction of the arrows, it will bewound up on the reel 23.

To r0tate the reel, thr drum 22 is provided v the shaft 33 is preferablythe one which imparts the reciprocating movement to the knife, and theconnections are such that the drum is rotated and the muslin advancedwhile the knife is moving upwardly. The construction to perform thisoperation is shown in Fig. 1, and consists of an eccentric 40 secured tothe shaft 33 and operating the strap 41, from which is extended a link42 pivotally connected at 43 to cross head 10. The throw of the link 31is adjusted by means of the familiar radial screw 34, in order to varythe amount of advance of the muslin to accommodate strips of differentwidths without excess spacing.

The operation of this apparatus can be readily understood.

The bias'strips as they are cut off from the leading end of thefrictioned fabric, fall onto the liner strip, and are carried by itto'the rear of the machine, where they are rolled up with the liner. Inthis manner, the separate strips are kept from contact with each other,and the machine performs automatically. the-operation of the workformerly required of two operators. lVhen a roll is filled, it may beremoved by taking away the rear side 35 of the guide" which is madeseparate for this purpose, t5

and a new one substituted.

The roll or .package of bias strips with the interposed liner which ismade by this machine, fo'rms the subject matter of a copendingapplication, Serial No. 34,803, filed 30 herewith.

It is obvious that various changes and modifications might be made inthe form of apparatus shown herein, without departing from the spirit ofthe invention as set ,55

forth in the appended claims.

Claims: 1 1. The combination with a machine for cutting a material intostrips, of a liner supply, means for guiding the liner under means forguiding the liner under thecutter, and means for winding up the linerwith the strips.

3. The combination with a machine for cutting fabric on the bias, aliner supply,

means for guiding the liner under the cutter and means for drawing theliner under the cutter and winding it up with the bias strips.

4. The combination with a bias cutter of a liner supply and means fordrawing the liner from the supply under the cutter and winding it upwith the bias strips.

5. The combination with a bias cutter,

a liner' supply, means for intermittently drawing the liner from thesupply under J. J. SHEA.
